pre vs. post increment operator – benchmark

A recent Visual C++ team’s comment on reminded me a hot topic that exists in C++ programming world: there is a long discussion of using pre versus post increment operators, specially, for iterators. Even me I was witness to a discussion like this. The discussion started from a FAQ written by me on

Base on that VC++ team’s tweet related to’s research I decided to create my own benchmark base on single and multicore architectures. For those that don’t know Viva64 is a company specialized on Static Code Analysis.
Starting from their project I extended the tested for other STL containers: std::vector, std::list, std::map, and std::unordered_map (VC++ 2010 hash table implementation).
For parallel core tests I used Microsoft’s new technology called Parallel Pattern Library.
